ATC and piloting (either GA or Airline) are very different jobs. If ATC's were paid the same as GA pilots, there would be no one left (*cheers from the crowd because of non-existant terminal fees*).
As a pilot, I am squirming at the new landing fees too. Please remember that it is not the individual controllers that are upping the terminal fees or trying to make it hard to make a buck for pilots.
Also remember that as a GA pilot there is at least the faint hope for everyone of becoming well-paid airline pilots, whereas there is but one employer of ATC in Australia. This is one of many reasons for the conditions of employment for ATCs.
But back to the topic at hand, ATC remuneration is not the topic. Cross-subsidisation is the problem.
